Monitoring and Predicting Agricultural Drought: A Global Study
Author: Vijendra K. Boken et. al. | Size: 4.90 MB | Format:PDF | Publisher: Oxford University Press, USA | Year: 2005 | pages: 496 | ISBN: 019516234X
Book Description:
Agricultural droughts affect whole societies, leading to higher food costs, threatened economies, and even famine. In order to mitigate such effects, researchers must first be able to monitor them, and then predict them; however no book currently focuses on accurate monitoring or prediction of these devastating kinds of droughts. To fill this void, the editors of Monitoring and Predicting Agricultural Drought have assembled a team of expert contributors from all continents to make a global study, describing biometeorological models and monitoring methods for agricultural droughts. These models and methods note the relationships between precipitation, soil moisture, and crop yields, using data gathered from conventional and remote sensing techniques. The coverage of the book includes probabilistic models and techniques used in America, Europe and the former USSR, Africa, Asia, and Australia, and it concludes with coverage of climate change and resultant shifts in agricultural productivity, drought early warning systems, and famine mitigation. This will be an essential collection for those who must advise governments or international organizations on the current scope, likelihood, and impact of agricultural droughts.

This second edition has been revised by the authors to include updated codes and standards information, solutions to technical problems, additional references, and clarifications to the text. Corrections were also made to some formulae, text, tables and drawings. This book offers straightforward, practical techniques for pipeline design and construction, making it an ideal professional reference, training tool, or comprehensive text. The authors present the various elements that make up a single-phase liquid and gas pipeline system, including how to design, construct, commission, and assess pipelines and related facilities. They discuss gas and liquid transmission, compression, pumps, protection and integrity, procurement services, and the management of pipeline projects.

there is considerable detail of the various boundary conditions that may be imposed on the basic pipe flow. But the main feature of the book is in the very detailed description of how to use the basic water hammer (WTHM) program which is available on a diskette, suitable for use with a PC, together with input data files for the examples described in the text. This book is obviously a useful tool for engineers concerned with practical problems of unsteady flow in water-pipe systems of great complexity.
Journal of Fluid Mechanics
The physical principles of water hammer are explained in this volume. The basic mathematical methods of solution of water hammer and ways of limiting its effects are covered. Detailed description is given of the method of characteristics and the corresponding programs for personal computers, which enables solution of water hammer in a wide variety of hydraulic systems encountered in practice. Examples are given of solution of water hammer of common pipe-line systems as well as calculation of the steady state of flow, the determination of discharge through a pipe-line, measurements of characteristics of valves, pumps, turbines, determination of the operating régime of a valve in order to ensure a desired pressure and discharge curve, etc. This book will be of interest to those civil, mechanical and petroleum engineers dealing with the design and operation of hydraulic systems.

A valuable, well-prepared and thought-provoking collection of case studies with solutions... it can certainly be recommended.,Journal of the Chartered Institution of Water and Environment Management.
Water hammer, or the study of fluid transient behaviour, is one of the most common problems in the water engineering community. This book covers the many causes and solutions in a practical way and is an essential reference for all those concerned with the flow of liquids, not just water, in pipe systems. It follows on from the authors' previous monograph on the problems and solutions of water hammer and presents common problems in the form of case studies.
This is an interesting and useful read for practising engineers working in this area and it will enable them to make comparisons with their own problems. Also the practical nature of the book makes it useful for civil engineering departmental libraries and departments where hydraulic design is taught.
